Abstract: 
Absolute and energy-scanned electron-impact ionization cross sections of Xe24+ ions in their ground level have been measured by employing a crossed-beams technique in the collision energy range from below threshold to 1000 eV. Direct ionization and excitation-autoionization cross sections were calculated using a detailed level-to-level distorted-wave method. Large discrepancy between the theoretical result, only including these two processes, shows the importance of additional ionization channels via resonant-excitation double autoionization (REDA). The carefully investigated convergence trend of REDA processes with the principal and angular-momentum quantum numbers of the recombined electron, n' and l', respectively, shows that sufficiently large n' and l' have to be included in the calculation of the total REDA contribution to correctly interpret the experiment.
